United States Patent | 5,169,298 |
Hekman ,   et al. | December 8, 1992 |
A constrained rotary vane compressor having a rotor-vane assembly within a stator often exhibits unwanted noise and vibration effects. The present invention offers a design and method to decrease noise and vibration effects of such compressors by the incorporation of an oil skive formed in the interior wall of the stator. The oil skive rids the vane tips of any excess liquid which may have collected on the rotating vanes, which otherwise may impact certain interior regions of the stator resulting in unwanted noise and vibration of the compressor.
